In this paper, we introduce symmetric variable nodes, and investigate how they can be used to advantage in decision diagrams. We consider totally-symmetric and partially-symmetric functions as well as functions with partial symmetries. The identification of symmetric variable nodes is investigated as is the uniqueness of the resulting representation. A principal advantage of the new node type is that it often reduces the depth of the decision diagram. We consider the effect this has on the circuits that can be directly identified from decision diagrams.","PeriodicalId":403347,"journal":{"name":"Proceedings of 26th IEEE International Symposium on Multiple-Valued Logic (ISMVL'96)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126820731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One could reasonably argue that all her original research properly belongs to Mathematical Logic, more precisely to the sub-field of Algebraic Logic. As a natural consequence of her previous work on non-classical logics, in the seventies she began to study several logics motivated by computational questions, but still the spirit of her original contributions retained the same algebraic flavour. Even the introductory book (1973) bears this mark: it contains elementary set theory with special attention to ordered sets, mathematical logic, and abstract algebra.","PeriodicalId":403347,"journal":{"name":"Proceedings of 26th IEEE International Symposium on Multiple-Valued Logic (ISMVL'96)","volume":"822 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133848695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It follows from this that the fraction of symmetric multiple-valued functions that have planar ROMDDs approaches 0 as n approaches infinity. Further, we show that the worst case and average number of nodes in planar ROMDDs of symmetric functions is n/sup 2/(1/2-1/2r) and n/sup 2/(1/2-1/(r+1)), respectively, when n is large.","PeriodicalId":403347,"journal":{"name":"Proceedings of 26th IEEE International Symposium on Multiple-Valued Logic (ISMVL'96)","volume":"220 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121308335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The latter decision diagrams are derived from partial Complex Hadamard Transform.
